Evaluating Forage Cover Crop Mixes for the Desert Southwest

Cover crops are essential tools to improve soil health and productivity1. Traditionally, cover crops are used as ‘green manures’ where the cover crops are not harvested but incorporated into the ground to boost soil health and fertility. Therefore, it has become a common perception that cover crops are meant to be incorporated into the soil. In the desert Southwest, water scarcity forces the producers to utilize water more strategically, and green manure cover crops may not be an economically sustainable option for farmers in the desert.
